Determined to get Adele's attention, Tracy started an online campaign on change.org with the emotional plea: "I have a very sick daughter who has cerebral palsy, epilepsy, can't walk or talk and is tube-fed, she has recently became bed-bound. She listens to Adele from she gets up in the morning until her bedtime.

"All I am asking for is for Adele to FaceTime wee Rebecca or send her a video message. It would be her dream come true, Please, please help me for my beautiful sick little daughter."

Numerous emails were sent to Adele's manager with no response. Then, to the family's surprise, the chart-topper took time out from her sellout concerts at the SSE Arena to visit disabled Rebecca at her Short Strand home.

The blind 12-year-old was given just six months to live by doctors in December, but despite her tragic prognosis her joy is ignited each day when mum Tracy plays Adele songs to her. Her family said just hearing the star's albums lights up her face and her life.

Mum Tracy said she was overjoyed about the visit.

"I can't believe it, I'm just over the Moon," added the mother-of-three, who is also a big fan.

"My daughter got to meet the person that she loved, and that's what I'll always take with me for the rest of my life.

"Adele played with her hair and held her hand and asked her all about Frozen. She was really lovely."

Kind-hearted Adele also offered the family free tickets to see her concerts, which were over two nights.

The unannounced arrival was a welcome surprise, not just for Tracy and Rebecca, but for adoring fans across Northern Ireland.

Joanna posted: "My baby sister's dream just came true, Adele came to visit her! So happy."

Nuala Doherty commented: "That's amazing, I'm so delighted for you all. Credit to Adele for making this sick child's dream come true. xx"

Nicole McGrillen added: "This made me so happy! Over the moon for you, so glad she got to meet her xxx."

The pictures were also posted on Twitter by Sinn Fein councillor Niall O'Donnghaile, who wrote: "Thank you so much Adele for visiting the beautiful Rebecca in the Short Strand today. Made her and (mum) Tracy's year!"
